A club with 50 college students is doing volunteer work this semester. Each student is volunteering at one of four locations. He

Yuliya22 [10]

Answer: Our required probability is 0.58.

Step-by-step explanation:

Since we have given that

Number of students worked in Nursing home = 11

Number of students worked in Tutoring center = 13

Number of students worked in Soup kitchen = 8

Number of students worked in Library = 18

Total number of students = 50

Since 3 students are selected from the club.

We need to find the probability that none of the three students volunteer at the soup kitchen.

So, Remaining students would be 50-8 = 42

So, probability that none of three students at the soup kitchen is given by

$\dfrac{^{42}C_3}{^{50}C_3}\\\\=0.58$

Hence, our required probability is 0.58.

According to a survey on us population, the probability that a man will live seventy-five years is 0.62 and that he will live up

Vsevolod [243]

The answer is 3.71%

Given: .62 probability of reaching 75 years old and 0.023 probability of reaching 85 years old
Since Mr. Clooney already reached 75 years old, we'll divide the probability of reaching 85 by the probability of reaching 75.
.023 / .62 = .0370967742 x 100 = 3.71%

Why? Assume there are 1000 men who were born at the same time.
0.62 * 1000 = 620 of them will make it to 75.
0.023 * 1000 = 23 of them will make it to 85.
The proportion of those who will make it to 85 assuming that they already made it to 75 will be 23 / 620 = 0.0370967742 (same as above)

Explain how you can solve 40 × 16 by breaking apart the numbers.

Aleksandr-060686 [28]

Do 40x10=400. Then do 40x6=240. Lastly, add 400+240=640.
